Application ined .M ay 1', 1911. Serial No. '$24,281.

To all/whom# may concern:

`Be it known that I, `WILLIAM J. Bollani), a eitizeneof the United States, lresiding at Bufalo injthecounty of Erie and State-of New York, have invented new-and useful Improvements in Water-Heaters, of which the following is a specification.

'My invention .relates to improvements in water `heatersA and 4more particularly to a heater adapted to bea-pplied to the ordinary pressure'boiler.

The primary object of my invention is the .production of a heater adaptedto be applied to "the .ordinary pressure boiler so as to heat the water contained therein.

Another object of my invention is the provision of a -heater of this type which can be removed from or adjusted lengthwise on the pressure boiler and which `is. provided with a burner whose flame acts directly against said pressure boiler.

, Still another object of my vinvention is 'the of this type having provision of a heater u for cooking, broil- Further objects are to constructa heater having two chambers, each provided with a burner and having an escape pipe 'for the smoke and fumes common to bot-h chambers; to provide aheater having all but one of its sides closed and the upper and lower walls vat. their innerends concaved to conform to the curvature of the boiler so that the latterv serves to' close the open side of the heater.;

l and .to otherwise improve on water 'heaters now in use.

By constructing a boiler with the above f objects in view, I am enabled to heat the water while contained in the pressure boiler instead of heating the same at a point out`vv sideof the boiler, thus making'it unnecessary lto. employ the `large number if pipes now employed 'on water heaters used in connection with prcssiu'eboilersas l dispense with the circulating pipe system owing to the fact that the water is heated in the boiler in quantity and only as'required. l

My invention consists in a heater applied to the' exterior of a pressure boiler and having therein a burner whose Idame is directed against theboiler to heat the water therein.

It also consists of a heater having a ca sing closed on all but one side and having its open side closed by the pressure boiler.

It further consists in a detachable `heater adjustable lengthwise of the boiler; in the provision o'f a cooking section and a water heating section; and 'of a smoke escape Hue common to both sections; and it still further consists -in the construction, `arrangement, and combination of parts to be hereinafter described and particularly pointed out in the subjoined claims.

lIn the drawings,-Figure 1 isa perspective view -of a .pressure boiler and a water heater constructed according to my inven tion-and applied to said boiler. Fig. 2 is a side elevation of a portion of a pressure boiler having my improved water heater applied thereto and shown in central vertical section. Fig. 3 is a horizontal section taken on line 1f-y, Fig. 2. Fig. 4 is a transverse vertical section taken on line 2 2, Fig. 2. Fig. 5 is a fragmentary side elevation showing a portion of the heater with its opening for permitting the lighting of the burner in thewater heating section, and the adjacent portion of a boiler.

Referring now to the, drawings in detail, in which similar numerals of reference refer to similar parts in the several figures, the reference numeral, 6 designates the pressure boiler, which has a feed pipe 7 and a water outlet pipe 8, the latter leading thea-hot water to any suitable point for use.

The heater is designated by the numeral 9 and comprises ya casing having an outer end wall 10, sidewalls 11,a topwall 12, and a .bottom wallv 13., The vcasing is Lpreferably made in widthso thatits sidewalls embrace a portion of the lboiler and its top and bottom walls are made concaved at=the1r inner ends to conform to the curvature of the boiler so that a close fit is obtained between the boiler and heater and so that the boiler effectively closes the inner end of `the heater. Se ental -securin bands 14 are secured to t e sidewalls lo the heater and are continued from such points around the boiler until they meet, said bands being rovided with outstanding lugs 15 at t eir meeting ends, through which are assed bolts 16 having nuts 17 threaded t ereon and with said bolts serving to rigidly secure theheater to the boiler. The interior of vthe lcasing is divided iinto two sections or stoves.

same being arranged in two series, one series supplyingair to the segmentally shaped inner chamber and the other to supply .air to the outer chamber.

Arranged in the inner chamber between the boiler and the dividingl wall 20 is a burner 23 lying in proximity to the surface of the boiler and extending through one of' the side walls of the heatercasing, it being provided outside of said casing with an air mixer 24 and connected by means of said air mixer with a supply pipe 25 having a valve In the top wallof the casing above the Lsegmentally shaped inner chamber or water heating section, is formed an opening 31 from which extends an upstandmg liange having connected thereto' an escape flue 32 for the escape of smoke or fumes of the gases, which flue may be connected to a chimney or be otherwise arranged for the roper disposal of the smoke and fumes.

he smoke 'and fumes, if any, in the outer chamber pass through the 'openings 21 in the dividing wall 20 and enter the upper end of the inner chamber 18, from .w ch they esca through the flue 32, and the smoke fumes o the gas from the water heating burner 23 ass directly upward and escape through sai flue. The airopenings 22 in the bottom wall of the .casing provide the necessary air for feeding the burners to obtain an eiective llame; and the openings in the top walll admit of cooking in a manner similar to ordinary gas cooking The burners 28 in the outer chamber may be li hted through the griddle openings and for t ev purpose ofrendering the water heating burner in the inner casing accessible to permit of easily 1i hting the same, an open.-

' ing33 is provide in one ofthe-side Walla 55 of the casingwhich ma be closed by a pivf oted lid 34, as'clearlyl s own in Fig. `l.A

I have herein shown my invention in vwhat I vnow consider avery practicable form; butA it is clear that cha in shape, construction, and minor details ma be resorted to without departingfrom e principle in-` .volved or sacrificing-an of the advanta th X.l Se A opening' and an escape openiii griddle A signature in the other a water heating section between my invention, what said cooking section Vand .the Aboiler having a burner in operative arrangement to said boiler and an 'escape flue.
